To all whom *it may concern:

Be it known that I, EDWIN RUSSELL, a citizen of the United States,residing at Kansas City, in the county of W'yandotte and State ofKansas, have invented certain new and 'useful Improvements in Pneumatic-Tire Protectors, of which the following is a speci- Iication. A

My invention relates to improvements in pneumatic-tire protectors, andmy object is' .to Iproduce a device of this character which 'Wi lprolong the lives of pneumatic-tires and revent the same from becomingpuncturedgwhile in use on automobiles.

' A further object is to rovide a simple device o'f this character wlich can be readily applied to or removed from the tire, and which will'prevent the wheels of an automobile lfrom slipping on wet pavements. Afurther object is to provide a device of this character which can beapplied to the ex/terioraof 'the tire to prevent the inner tube vthereoffrom becoming pnnctured.

In order that the invention may be fully understood, reference will -nowbe made to the accompanying drawings, in which: l Figure 1 represents aside elevation of an Lautomobile wheel provided with my protector, thespokes of the wheel being omitted, Fig. 2 'is an enlarged side elevationof a portion ofthe same.- Fig. '3 is a vertical, longitudinal, sectionalview of three sections of myv device. Fig. 4 is a cross .section on lineIV-IV of Fig. 1.

1 designatesthe felly of the wheel; i2, the metallic rim secured tothefelly; and 3, the

outer tube of the tire secured to the 'metallic i .rirn,all of which areof ordinary construction, and -:form no part of the presentinvem tion,which latter ,consists of a series of res ilient overlapping diamondshaped shells or -sctions 4, cables 5 connecting said diamond- E fa'@1101 ing the sections in 4.5'

shells 'or sections, and a yoke 1 3 for position upon the outer portion.of the tire.

The shells or sections are provided with 'transverse' corrugations 7 toprevent the Wheels of the automobile from slippin/ii, and @Bch Section''tapers toward its front 'am rear Sides 8. and 9, res 'eetively, and isprovided with an exterior s oulder 10 and an interior shoulder y11,against which thel rear end of t e'prece section and theront enfdyofthe. succeeding section, respectively,l are ada ted'to 'a'.bnt. Thedepth of shoulders 10` an 11 equals the thiclmessof ends 8 and 9,-

so that said ends will be flush. with the adjacent portions of thesections instead of projecting therefrom and thereb injuring the tire,as would probably be t e case should the front end 8 of'eachsectionprojectbelow the adjacent portion of each succeeding section. Thesections taper toward their terminals 12 and are flexibly connected bythe cables 5 so that said sections may readily accommodate themselves tothe movements 'of the tire, when the Wheel is running, over the surfaceof a road.

Yolres 6 are heldin position on the Wheel" by a plurality of bolts 13,extending through the rims of the wheel, and etaining-nuts 14 engaging-the threaded ends of said bolts.

` Yolres 6 have outturned terminalsl which extend through enlargedlinksl? ofthe cable and are provided with retaining-nuts 1G to reliablyhold the links in position thereon and prevent the device ing on thetire.
